1.在预置式扭力扳手的使用中,首先要根据测量工件的要求，选取适中量程的预置式扭力扳手,所测扭力值不可小于扭力器在使用中量程的百分之二十,太大的量程不宜用于小扭力部品的加固,小量程的预置式扭力扳手更不可以超量程使
1. In the use of the preset torque wrench, first of all, according to the requirements of the measuring workpiece, select the preset torque wrench with moderate range, the measured torque value should not be less than 20% of the range of the torque wrench in use, too large range should not be used for the reinforcement of small torque parts, and the preset torque wrench with small range should not exceed the range
2.在使用预置式扭力扳手时,先将扳手方榫连接好辅助配件(如各类批嘴、套筒),确保连接已经没问题。在加固扭力之前,设定好需要加固的力值,并锁好紧锁装置,调整好方向转换钮到加力的方向，然后在使用时先快速连续操作4-5次，使扳手内部组件上特殊润滑剂能充分润滑，使预置式扭力扳手更准确，使用。
2. When using the preset torque wrench, first connect the square tenon of the wrench with the auxiliary accessories (such as all kinds of nozzles and sleeves) to ensure that the connection has no problem. Before strengthening the torque, set the force value to be reinforced, lock the locking device, adjust the direction conversion button to the direction of force application, and then quickly and continuously operate for 4-5 times before using, so that the special lubricant on the internal components of the wrench can be fully lubricated, and the preset torque wrench can be used more accurately.
3.测量时,手要把握住把手的,沿垂直于扭力扳手壳体方向，慢慢地加力，直至听到扭力扳手发出“塔”的声音，此时扭力扳手已到达预置扭力值，工件已加力完毕，然后应及时解除作用力，以免损坏另部件。在施力过程中,按照国家标准仪器操作规范,其垂直度偏差左右不应超过10度。其水平方向上下偏差不应超过3度,操作人员在使用过程中应保证其上下左右施力范围均不超过15度；
3. When measuring, hold the handle by hand and slowly apply force along the direction perpendicular to the shell of the torque wrench until you hear the "tower" sound of the torque wrench. At this time, the torque wrench has reached the preset torque value and the workpiece has been applied force. Then, release the force in time to avoid damaging other parts. During the operation, the verticality of the instrument should not exceed 10. The deviation of the horizontal direction should not exceed 3 degrees, and the operator should ensure that the force application range is not more than 15 degrees in the use process;

4.为了不使测量结果因水平和垂直方向上的偏差而产生影响,在测量时,应在加力把持端上施加一个垂直向下的稳定力值， 然后再手动加点力，这样操作可以让读数值更准确。
4. In order not to affect the measurement results due to the horizontal and vertical deviation, a vertical downward stable force value should be applied on the force application holding end during the measurement, and then the point force should be added manually, so that the reading value can be more accurate.
5.预置式扭力扳手的读数: 如果是带表扭力仪器，直接读取指针所指示的数据为测量数据值即可；如果是套筒加副刻度指示器，应先读取主刻度上的刻度值,再加上副刻度或微分筒上的刻度值之和为测量数据值。
5. Reading of preset torque wrench: if it is a torque instrument with a meter, the data indicated by the pointer can be directly read as the measured data value; if it is a sleeve plus sub scale indicator, the scale value on the main scale shall be read first, and then the sum of the scale values on the minor scale or differential cylinder shall be the measured data value.
6.预置式扭力扳手是测量工具，应轻拿轻放，不能代替榔头进行敲打等不正当行为，不用时请注意将扭力设为较小值，存放在干燥处。 扭力扳手应用范围较广,在加固扭力时,相对来讲比较简单，只需要设定其要求扭力值便可进行操作。
6. The preset torque wrench is a measuring tool, which should be handled with care. It can't replace the hammer for knocking and other improper behaviors. When not in use, please set the torque to a small value and store it in a dry place. Torque wrench has a wide range of applications. When strengthening the torque, it is relatively simple. You only need to set the required torque value to operate.
